RTX 3090 Desktop (24 GB VRAM, 64 GB RAM) — what it gives a model

Llama 3.2 Vision on RTX 3090 Desktop (24 GB VRAM, 64 GB RAM): memory by quantization

Which Llama 3.2 Vision sizes fit

What to watch out for

• 1 larger variant of Llama 3.2 Vision does not fit and would need CPU offload or different hardware.

RTX 3090 desktop limitations

• The cheapest route to 24 GB of VRAM, and the standard used-market recommendation for local LLMs.
• Older architecture: no FP8 acceleration, and higher idle power than a current card.

Recommended setup

Ollama or llama.cpp (CUDA/ROCm) — vLLM if you need concurrent serving

How these numbers are calculated

• Memory need = quantized weights + KV cache at 8,192 tokens (f16) + 0.8 GB runtime overhead.
• 24 GB of VRAM on the NVIDIA GeForce RTX 3090 at 936 GB/s.
• 64 GB of system RAM available for CPU offload when a model exceeds VRAM.
• Throughput is a memory-bandwidth roofline estimate, not a measurement. It is labelled "estimated" everywhere it appears.
• KV cache is computed from this model's published attention configuration.

FAQ

Can I run Llama 3.2 Vision on RTX 3090 Desktop (24 GB VRAM, 64 GB RAM)?
